Text to a Korean Friend: Cancelling and Rescheduling
You have 15 minutes in class to write a KakaoTalk message to 지우, a Korean friend your age. You have met three times and always use 반말. You promised to meet at 2 pm on Saturday at the library to study. Your soccer team now has a match at 1 pm, and you do not know when it ends. You need to cancel and suggest Sunday. Your draft is: '미안해. 나는 축구 경기가 있어서 갈 수 없어. 우리는 일요일에 만나자.' The teacher marks it for register, clarity, and grammar. You may use only learned patterns: -아/어서, -ㄹ 수 있어요, -자, -는데. You have no dictionary. The message must be three sentences and include an apology, a reason, and a new suggestion.
1. Evaluate the draft: what works, and what is unnatural or risky for a same-age friend?

Works: it includes an apology (미안해), a reason with -아/어서 (축구 경기가 있어서), and a suggestion with -자 (만나자). It uses 반말, which fits a same-age friend. Risky: '나는' and '우리는' are unnecessary; Korean drops pronouns when clear, and repeating them sounds translated. '갈 수 없어' is grammatically fine but direct; a softer opener like '지우야, 미안해' helps. Reasoning: the draft is understandable, but naturalness is part of the writing judgement, not just grammar.
2. Rewrite the message in three sentences that are clearer and more natural.

One good version: '지우야, 미안해. 토요일에 축구 경기가 있어서 2시에 갈 수 없어. 일요일에 같이 공부하자.' Why: sentence 1 apologizes and names the friend; sentence 2 gives the reason and the specific cancelled time; sentence 3 suggests a new day with -자. Pronouns are dropped because context is clear. If you want to be less direct, '일요일은 어때?' is also polite, but it is a question rather than a suggestion. Reasoning: three sentences, three jobs: apology, reason, repair.
3. Why is '갈 수 없어' acceptable here, and when would '못 가' be better?
Read the worked answer
'갈 수 없어' means 'cannot go' and is acceptable because it uses the learned pattern -ㄹ 수 없다 and is clear. '못 가' also means 'cannot go', often emphasizing an external constraint; it is shorter and more conversational. Here the constraint is a soccer match, so '못 가' would also fit. Judgement: for an assessment, use the pattern you can control; do not add complex softening you cannot spell. Both are correct, but consistency and clarity matter more than sounding advanced.
